1) Error Handling (CVE-ID: CVE-2022-25762)

The vulnerability exists due to an error in documentation for the EncryptInterceptor, which incorrectly stated that it enabled Tomcat clustering to run over an untrusted network. A remote attacker can perform a denial of service attack against the exposed EncryptInterceptor.
